  • the ink viscosity at 100 rpm in an EM rotational viscometer is preferably from 40 to 200 mPa ⁇ s.
  • the retractable ballpoint pen 1 in the present embodiment has a configuration in which, when the friction body 9 is downward and an axial line J of the barrel is vertical to the writing surface in a state where the ballpoint pen tip 12 is retracted into the front barrel 2, the tangent S to both the friction body 9 and the operating portion 5A becomes at degrees or more relative to the writing surface.
  • the friction body 9 when a user uses the friction body 9, it is possible to use without worrying about contact of the operating portion 5A with the writing surface.
  • the tangent S to both the friction body 9 and the operating portion 5A when the friction body 9 is downward and the axial line J of the barrel is vertical to the a writing surface is preferably 60 degrees or more and most preferably 70 degrees or more.
  • the pressing force of the coil spring to press the ball is not particularly limited, it is possible to obtain good writing and impact resistance performance by making it more than the product weight and also not more than 30 g. This is because, when the pressing force of the coil spring to press the ball is less than the product weight, it is difficult to suppress the movement of the ball due to an impact and ink leakage is prone to occur. It is also because, when the pressing force of the coil spring to press the ball is more than 30 g, start writing performance and writing texture decrease.
  • the ball diameter is not particularly limited. It is preferred because good handwriting and writing comfort is obtained by, as the embodiment, using a ball of ⁇ 0.4 mm or less, having clearance in the vertical direction of the ball from 30 to 50 ⁇ m, and having an ink consumption per 100 m from 150 to 300 mg. This is because it becomes difficult to increase the ink consumption as much as the ink consumption per 100 m from 150 to 300 mg when the clearance in the vertical direction of the ball is less than 30 ⁇ m.
  • the clearance in the vertical direction of a ball exceeds 50 ⁇ m using a ball with not more than ⁇ 0.4 mm, the thickness at the front end of the tip is thin and the ball retaining force decreases, so that from 30 to 50 ⁇ m is most preferred.
  • the ball diameter is preferably from ⁇ 0.3 mm to ⁇ 0.4 mm. It is possible to obtain the ink consumption per 100 m by writing with a write testing machine in conditions of load of 100 g, writing speed at 4 m/min, writing angle at 70 degrees, and 20°C in accordance with JIS S 6054 and calculating an ink consumption (average value often) per 100 m.
  • F mV/t
  • impact force F [N]
  • mass of object mass of object
  • deceleration time is t [s]
  • the thickness of the tip end part 13A becomes thin and a dent is prone to be made when dropping.
  • the retractable writing instrument placed horizontally on a desk is prone to move by being hit by a hand, an elbow, a book, a notebook, or the like, and as a result, it is prone to drop, so that it is preferred that the product weight is 5 g or more.
  • the operating portion 5A as a projecting area is a plate piece having a longitudinal cross-section in an arc shape that also work as a protrusion to prevent rolling when the writing instrument is placed horizontally on a desk and is provided with a hole portion 5C to attach a charm, it is also possible to integrally form or attach a clip.
  • the barrel main body is configured with the front barrel, the middle barrel, and the rear barrel in the present embodiment, it is not particularly limited as such.
  • the barrel main body (front barrel, middle barrel, rear barrel) and the operating body are formed by a synthetic resin, such as polycarbonate, polyethylene, and ABS, and metal, it is preferred that the operating body at least is formed by a transparent or translucent synthetic resin. This is because, by making the operating body 5 to be transparent or translucent as illustrated in Fig. 6 , it is possible to not easily reduce the visibility of handwriting even when the operating portion 5A comes into eyesight while using the friction body 9.
  • the maximum outer diameter of the rear end of the barrel is designed to be from 1.0 times to 1.5 times the maximum outer diameter of the friction body to suppress obstruction to handwriting by the rear end of the barrel while using the friction body for enhancement of the visibility of the handwriting.
  • the maximum outer diameter of 1/3 or more of the entire length of the writing instrument, even more preferably 1/2 or more and most preferably the entire writing instrument, from the barrel rear end of the friction body is also set to be from 1.0 times to 1.5 times the maximum outer diameter of the friction body, thereby being capable of further enhancing the visibility of handwriting.
  • Many of general notebooks are provided with horizontal ruled lines at 7 mm pitch, and those having 8 mm and 10 mm pitches are also often commercially available. It is therefore preferred that the maximum outer diameter of the friction body is 7.0 mm or less.
  • the present embodiment exemplifies a retractable ballpoint pen including a retraction mechanism made with a rotating cam for convenience
  • the retraction mechanism is not particularly limited. Considering the operability and the like, it is preferred to use a retraction mechanism made with a rotating cam.
  • the retractable ballpoint pen of the present invention has easy thermochromism only in a desired area, it is widely applicable to use with notebooks and pocketbooks.
  • retractable ballpoint pen of the present invention may be used without limitation in the retraction mechanism, it is widely applicable as a retractable ballpoint pen.
